Split ticket handling

ABSTRACT

This disclosure describes techniques and arrangements for splitting one or more items from a ticket to another ticket. Some techniques and arrangements facilitate the splitting of one or more items from an open ticket to one or more split tickets. In some implementations, a foster ticket is utilized to account for items associated with split tickets. Other techniques and arrangements include providing split ticket suggestions. In some implementations, split ticket suggestions are provided based on historical ticket information and/or customer information.

BACKGROUND

Typical point-of-sale (POS) devices used by merchants create relativelysimple tickets that document items ordered by customers and paymentinstruments used by the customers to pay for their items. Typically, anexample ticket would track the items ordered by a customer, the cost ofthe items, and how the customer paid for these items. While thesetraditional tickets are effective at ensuring that a customer receiveswhat she orders—and is charged as such—the traditional tickets, and thePOS devices that provide them, perform very limited functionality.

DETAILED DESCRIPTION

This disclose describes, in part, techniques and arrangements forsplitting one or more items from a merchant ticket to one or more othermerchant tickets. Some implementations described herein includetechniques and arrangements for making suggestions with respect toticket splitting.

In a non-limiting example scenario, a group of customers may order menuitems (e.g., food, drinks, etc.) at a restaurant. The waiter attendingto the customers may use a point-of-sale (POS) device to generate aticket that tracks the items ordered by the customers. When thecustomers finish their meal, the waiter may ask the customers whetherthey would like to pay on a single check or on separate checks. Thecustomers may choose to split the check in whatever manner suits them.For example, the customers may want to split the check such that eachcan pay for the respective items they ordered. In another example, agroup of four customers consisting of two couples may want to split thecheck into two checks in accordance with the items ordered by eachcouple. The waiter may use the POS device to split the ticket into twoor more tickets. That is, one or more items of the original ticket maybe split from the original ticket to one or more other tickets (e.g.,one or more new, “split tickets”).

The POS device may communicate with one or multiple servers. Forexample, a server (or other type of computing device) of a paymentprocessor may be configured to, among other things, process payments formultiple merchants including the restaurant merchant of thisillustrative example scenario. The server may additionally oralternatively be configured to facilitate the handling of split ticketsas described herein. The POS device and the server may communicate tocooperatively track various aspects of tickets (including splittickets), such as items, customers, costs, etc. associated with eachticket.

In some instances, tickets described herein may be known as opentickets, which record interactions between customers and merchants. Forinstance, when a particular customer from a group orders an item fromthe merchant, the merchant may add this item to the open ticket. Whenanother customer from the group orders another item from the merchant,the merchant may likewise add this item to the open ticket, and maycontinue doing so until the group has finished ordering items. That is,open tickets track interactions of a customer (or multiple customerspart of a common group at the merchant) and a merchant over time. Theseinteractions include items ordered, tenders used, notes added by themerchant, and tags selected by the merchant, as well as timinginformation noting when each of these events occurred. As such, the opentickets serve as a canonical representation of a transaction between thecustomer and the merchant. When one or more customers provide payment(i.e., tenders) to the merchant, the merchant may note the tender(s)used on the open ticket to settle the cost of the ordered items.

In some instances, an open ticket may be created prior the customer evenarriving at a merchant. For instance, a merchant may create an openticket upon a customer requesting to create a reservation with themerchant at a specified future time. That is, in response to receivingsuch a request, a device of the merchant may generate an open ticketthat will later be used by the merchant to track interactions with thecustomer at the specified future time, such as the items ordered by thecustomer, the tenders used by the customer, and the like. By doing so,each interaction between the customer and the merchant from the timethat the customer first expressed an interest in patronizing themerchant (i.e., when the customer requested to create a reservation) tothe time at which the customer closes the transaction with the merchant(i.e., when the customer pays and/or when the last item is delivered tothe customer) may be noted for subsequent analysis.

In some implementations, a user interface (UI) presented on a display ofthe POS device may include a visual representation of a ticket. Thestate of a ticket on the POS device and/or the UI of the POS device maybe referred to herein as a “UI state” of the ticket. Likewise, the stateof a ticket on the server may be referred to herein as a “server state”of the ticket.

As will be described in further detail below, the POS device and/or theUI of the POS device may be operable in an open ticket mode to generatean open ticket. In some examples, the UI of the POS device may presentan option for switching or transitioning from the open ticket mode to asplit ticket mode. In the split ticket mode, the open ticket may besplit into multiple tickets. The POS device may receive inputs thatcause manipulation of a ticket. For example, a merchant may use the POSdevice to manipulate (e.g., save, cancel, split, add item(s) to, removeitem(s) from, add customer to, remove customer from, etc.) an openticket while operating the POS device in the open ticket mode and/or tomanipulate a split ticket while operating the POS device in the splitticket mode.

In some examples, the POS device may track and/or store the UI state ofone or more tickets in a memory of the POS device. The POS device maycommunicate with the server based at least in part on actions performedat the POS device with respect to a ticket. For instance, the servermay, in response to receiving an indication that the ticket has beenmanipulated at the POS device, initiate or update the server state ofthe manipulated ticket and/or the server state of another ticket that isassociated with the manipulated ticket.

In various implementations, the server may generate one or more fostertickets. As described herein, a foster ticket may be a ticket at theserver used to track ticket information associated with one or moretickets at the POS device. For instance, the foster ticket may be usedto account for items and/or tickets that are capable of beingmanipulated via the POS device.

In another non-limiting example scenario, a POS device associated with amerchant may generate an open ticket for multiple items ordered by acustomer. The open ticket may be generated using the open ticket mode ofthe POS device. The multiple items of the open ticket may include afirst item and a second item. Then, the POS device may be transitionedfrom the open ticket mode to the split ticket mode. While in the splitticket mode, the second item may be split from the open ticket to a new,split ticket. At this point, the UI state may include the open ticket asa first ticket and the split ticket as a second ticket, where the firstticket includes the first item and the second ticket includes the seconditem.

As will be discussed in further detail below, various informationassociated with the tickets may be logged. For instance, a parent-childrelationship may be established between the first ticket in the secondticket, where the first ticket is a parent of the second ticket, and thesecond ticket is a child of the first ticket. The POS device and/or theserver may log parent-child relationship between tickets. Additionallyor alternatively, the POS device and/or the server may log eventsassociated with the tickets. For instance, the POS device and/or theserver may keep an event log that records events such as, but notlimited to, the splitting of the second item from the first ticket tothe second ticket. The POS device and/or the server may, in some cases,log information in a single log file or in multiple log files. In somecases, the logged information may be used to trace the UI state and/orthe server state forwards or backwards to respond to actions that mayhave a dependency on the history of a ticket, such as reverting to aprevious ticket state when a ticket split is canceled.

Meanwhile, the server state may include a first foster ticket associatedwith items available in the UI state, including the first item and thesecond item. In various implementations, the first foster ticket may beassociated with the original open ticket (i.e., the first ticket in thisexample). For instance, the first foster ticket and the first ticket maybe associated by way of a same identifier (ID).

Continuing with the illustrative example discussed immediately above,the first ticket may be saved at the POS device. The POS device may savethe first ticket in association with the first item and/or send arequest to the server to save the first ticket in association with thefirst item. Furthermore, the POS device may dismiss the first ticketfrom the UI presented on the display of the POS device. That is, thefirst ticket may be removed from the UI of the POS device, leaving thesecond ticket remaining in the UI. Because the first foster ticket isassociated with the first ticket, and the first ticket has beendismissed from the UI of the POS device, the server may replace thefirst foster ticket with a second foster ticket that accounts for theitems that are remaining in the UI of the POS device. The second fosterticket may be associated with the second ticket and with the items thatare remaining in the UI of the POS device, including the second item.

Additionally or alternatively, the server and/or the POS device may beconfigured to provide intelligent suggestions with respect to ticketsplitting. For example, the server may receive ticket information fromPOS devices associated with multiple merchants. The ticket informationmay be associated with tickets generated at least partly via the POSdevices. The server may utilize this ticket information to provideticket splitting suggestions to the POS device.

In some cases, the ticket splitting suggestions may be based at least inpart on relationships between items and/or types of items. For instance,the server may determine, based at least in part on the ticketinformation, that a number of tickets include an order of fries alongwith an order of a hamburger. The server may store a flag associatedwith a hamburger type of item and fries type of item. The server mayreceive a list of items associated with an open ticket generated by aPOS device associated with one of the merchants. The list of items mayinclude an order of a hamburger and an order of fries along with otheritems. The server may determine that the hamburger item of the openticket is of the flagged hamburger type. Similarly, the server maydetermine that the fries item of the open ticket is of the flagged friestype. As a result, the server may send a split ticket suggestion to thePOS device. The split ticket suggestion may cause the POS device tosuggest (e.g., via the UI) to split the hamburger item and the friesitem from the open ticket to a new, split ticket.

In some instances, the ticket splitting suggestions may additionally oralternatively be based at least in part on relationships betweencustomers and items (and/or types of items). For example, the server maydetermine, based at least in part on the ticket information receivedfrom the POS devices associated with multiple merchants, that aparticular customer has ordered a first type of item and a second typeof item together in a number of tickets. As such, the server mayassociate the customer with the first type of item and the second typeof item. The server may receive a list of items associated with an openticket generated by a POS device associated with one of the merchants.The list of items may include a first item and a second item. The openticket and/or the list of items may indicate an association between thefirst item and the customer, and an association between the second itemand the customer. The server may determine that the first item is of thefirst type of item associated with the customer, and that the seconditem is of the second type of item associated with the customer. As aresult, the server may send a split ticket suggestion to the POS device.The split ticket suggestion may cause the POS device to suggest (e.g.,via the UI) to split the first item and the second item from the openticket to a new, split ticket.

The foregoing example techniques and arrangements for making suggestionswith respect to ticket splitting are non-limiting and are merelyprovided for illustrative purposes. Various implementations, includingthose discussed below with reference to the figures, may includeadditional or alternative techniques and/or arrangements for makingticket splitting suggestions.

As used herein, a merchant may include any business engaged in theoffering of goods or services for acquisition by customers. Actionsattributed to a merchant may include actions performed by owners,employees, or other agents of the merchant, and thus no distinction ismade herein unless specifically discussed. In addition, as used herein,a customer may include any entity that acquires goods or services from amerchant, such as by purchasing, renting, leasing, borrowing, licensing,or the like. Hereinafter, goods and/or services offered by merchants maybe referred to as items. Thus, a merchant (or an employee of themerchant) and a customer may interact with each other to conduct atransaction in which the customer acquires an item from the merchant,and in return, the customer provides payment to the merchant.

As used herein, a transaction may include a financial transaction forthe acquisition of goods and/or services that is conducted between acustomer and a merchant (or an employee of the merchant). For example,when paying for a transaction, the customer can provide the amount thatis due to the merchant using cash or other payment instrument (e.g., adebit card, a credit card, a stored-value or gift card, a check, throughan electronic payment application on a device carried by the customer,or the like). The merchant can interact with a merchant device, such asa POS device, to process the transactions, such as by inputting (e.g.,manually, via a magnetic card reader or an RFID reader, etc.)identifiers associated with the payment instruments. For example, apayment instrument of the customer may include one or more magneticstrips for providing card and customer information when swiped in a cardreader. In other examples, other types of payment cards may be used,such as smart cards having a built-in memory chip that is read by themerchant device when the card is “dipped” into the reader, aradiofrequency identification tag, or so forth.

For discussion purposes, some example implementations are describedbelow with reference to the corresponding figures. However,implementations herein are not limited to the particular examplesprovided, and may be extended to other environments, other systemarchitectures, other types of merchants, and so forth, as will beapparent to those of skill in the art in light of the disclosure herein.

FIG. 1 is a schematic diagram illustrating an example scenario 100 thatprovides context for the discussion of various scenarios with respect toFIGS. 2A-2E. In particular, FIG. 1 is an illustration of an examplescenario 100 occurring at a restaurant in which open ticket transactionsand ticket splitting may be performed.

Customers 102-108 are at the restaurant. A merchant 110 (e.g. a memberof the service personnel of the restaurant) is serving the customers102-108 at the restaurant. The customers 102-108 may order menu items byrequesting them from the merchant 110. In the example scenario 100,customer 102 orders item A, customer 104 orders item B, customer 106orders item C, and customer 108 orders item D. The merchant 110 createsan open ticket 112 for items requested by the customers 102-108 using amerchant device 114. A visual representation of the open ticket 112 maybe provided to the merchant 110 via a user interface 116 presented on adisplay of the merchant device 114. The merchant device 114 maycommunicate with one or more servers 118 to perform various functionsassociated with tickets, including the generation and handling of opentickets and split tickets.

As will be discussed in further detail below, the merchant device 114and/or the server 118 may include a split ticket handling module 120and/or a split ticket suggestion module 122. The split ticket handlingmodule 120 may function to facilitate the handling of split tickets. Thesplit ticket suggestion module 122 may function to provide suggestionsfor splitting tickets.

When the customers 102-108 finish their meal, the merchant 110 may askthe customers 102-108 whether they would like to pay on a single checkor on separate checks. The customers 102-108 may choose to split thecheck in whatever manner suits them. For example, the customers may wantto split the check such that each can pay for the respective items theyordered. That is, customer 102 may want to pay for item A only, customer104 may want to pay for item B only, customer 106 may want to pay foritem C only, and customer 108 may want to pay for item D only.Accordingly, the merchant 110 may operate the merchant device 114 tosplit items from the open ticket 112 to split tickets. As depicted, itemA is allocated to first split ticket 124, item B is allocated to secondsplit ticket 126, item C is allocated to third split ticket 128, anditem D is allocated to fourth split ticket 130. In variousimplementations, the first split ticket 124 may be the original openticket 112. In other words, items B-D may be split from the open ticket112 to new split tickets, while item A may remain on open ticket 112,which may also be considered a split ticket.

FIGS. 2A-2E show a schematic diagram illustrating an example process 200for handling split tickets in accordance with some implementations. Theexample process 200 illustrates a user interface (UI) state of ticketsand a server state of tickets.

At 202, the process 200 may generate a first ticket T(1) associated withitems A-D. For instance, the first ticket T(1) may be an open ticketgenerated by a merchant device while operating in an open ticket mode. Avisual representation of the first ticket T(1) may be presented via a UIof the merchant device. In some implementations, data structurescorresponding to tickets that are presented via the UI, such as thefirst ticket T(1) may be stored in a memory of the merchant device.

At 204, the process 200 may generate a first foster ticket F(1)associated with items A-D. The first foster ticket F(1) may beassociated with the first ticket T(1). In some implementations, thefirst foster ticket F(1) may be generated by the server(s) at leastpartly in response to being notified of the generation of the firstticket T(1). In other implementations, the first foster ticket F(1) maynot be generated until after being notified of a split ticket actiontaken with respect to the first ticket T(1). In some cases, the firstfoster ticket F(1) may be the first ticket T(1) designated as the firstfoster ticket F(1). In other cases, the first ticket T(1) and the firstfoster ticket F(1) may be separate entities, and may be treated as suchby the server(s). The server(s) may use foster tickets to account foritems and/or tickets at merchant device(s).

At 206, the process 200 may transition the merchant device(s) from theopen ticket mode to a split ticket mode. Items B, C, and D may be splitfrom the first ticket T(1) to a second ticket T(2), a third ticket T(3),and a fourth ticket T(4), respectively. Item A may remain on the firstticket T(1). At this point, the first ticket T(1) may be stored in amemory of the merchant device(s) in association with item A while theupdate to the first ticket T(1) may not yet be stored in the server(s).

At 208, the process 200 may save the first ticket T(1). For instance themerchant device(s) may receive, via the UI, one or more inputs thatcorrespond to a save of the first ticket T(1). In some implementations,certain other inputs and/or actions may cause a save or provide aneffect that is the same as, or similar to, a save of a ticket. Forexample, in some cases, an input corresponding to a print of a ticketmay cause the ticket to be saved.

At 210, the process 200 may save the first ticket T(1) in associationwith item A and replace the first foster ticket F(1) with a secondfoster ticket F(2) associated with items B-D. The second foster ticketF(2) may be associated with the second ticket T(2). For instance, theserver(s) may save the first ticket T(1) in association with item A inresponse to being notified of the save of the first ticket T(1) at themerchant device(s).

The server(s) may replace the first foster ticket F(1) because the firstfoster ticket F(1) was associated with the first ticket T(1), which hasbeen saved. The server(s) may generate the second foster ticket F(2) toaccount for the items remaining in the UI of the merchant device(s)and/or the tickets remaining in the UI of the merchant device(s),specifically, items B-D. In some implementations, foster tickets areassociated with the lowest ordinal ticket remaining in the UI of themerchant device(s). At this point in the process 200, the lowest ordinalticket remaining in the UI of the merchant device(s) is the secondticket T(2). Accordingly, the second foster ticket F(2) is associatedwith the second ticket T(2). In some examples, the second foster ticketF(2) may include an identifier that is correlated with an identifier ofthe second ticket T(2).

At 212, the process 200 may dismiss the first ticket T(1) from the UI ofthe merchant device(s). For example, the visual representation of thefirst ticket T(1) may no longer be presented via the UI of the merchantdevice(s).

At 214, the process 200 may save the second ticket T(2). For instance,the merchant device(s) may receive, via the UI, one or more inputs thatcorrespond to a save of the second ticket T(2).

At 216, the process 200 may save the second ticket T(2) in associationwith item B and replace the second foster ticket F(2) with a thirdfoster ticket F(3) associated with items C-D. The third foster ticketF(3) may be associated with the third ticket T(3). For instance, theserver(s) may save the second ticket T(2) in association with item B inresponse to being notified of the save of the second ticket T(2) at themerchant device(s). At this point in the process 200, the lowest ordinalticket remaining in the UI of the merchant device(s) is the secondticket T(2). Accordingly, the second foster ticket F(2) is associatedwith the second ticket T(2).

At 218, the process 200 may dismiss the second ticket T(2) from the UIof the merchant device(s). For example, the visual representation of thesecond ticket T(2) may no longer be presented via the UI of the merchantdevice(s).

At 220, the process 200 may exit the split ticket mode. For example, themerchant device(s) may receive, via the UI, one or more inputscorresponding to an exit of the split ticket mode.

At 222, the process 200 may load the third foster ticket F(3) into thecart. At 224, the process 200 may coalesce the remaining items, itemsC-D, into a single ticket.

Referring back to the dismissal of the first ticket T(1), at 212, whichleaves items B, C, and D on tickets T(2), T(3), and T(4), respectively,the process 200 may continue by saving the fourth ticket T(4), at 226.For instance, the merchant device(s) may receive, via the UI, one ormore inputs that correspond to a save of the fourth ticket T(4).

At 228, the process 200 may save the fourth ticket T(4) in associationwith item D and update the second foster ticket F(2) to be associatedwith items B-C. The second foster ticket F(2) may maintain itsassociation with the second ticket T(2) because the second ticket T(2)remains in the UI of the merchant device(s).

FIG. 3A is a block diagram illustrating an example of splitting an itemby type from a first ticket T(1) 302 to a second ticket T(2) 304. Thefirst ticket 302 may include multiple items of different types. Forinstance, the first ticket 302 may include item A and item B. Item B maybe split from the first ticket 302 to a second ticket 304, and item Amay remain on the first ticket 302. A parent-child relationship betweenthe first ticket 302 and the second ticket 304 may be established. Forinstance, the merchant device(s) and/or the server(s) described hereinmay log the parent-child relationship. Additionally or alternatively, aparent-child relationship may be established between item A and item Bmay, which may logged by the merchant device(s) and/or the server(s)described herein. Furthermore, the merchant device(s) and/or theserver(s) described herein may log a split event based on the splittingof item B from the first ticket 302 to the second ticket 304.

FIG. 3B is a block diagram illustrating an example of splitting an itemby quantity from a first ticket T(1) 306 to a second ticket T(2) 308.The first ticket 306 may include a quantity of a type of item that ismore than one. For example, the first ticket 306 may include a quantityof 5 of item A. A quantity of 3 of item A may be split from the firstticket 306 to the second ticket 308, and a quantity of 2 of item A mayremain on the first ticket 306.

FIG. 3C is a block diagram illustrating an example of splitting an itemfrom a split ticket to another split ticket. A first ticket T(1) 310 mayinclude a quantity of 5 of item A. A quantity of 3 of item A may besplit from the first ticket 310 to a second ticket T(2) 312, a quantityof 1 of item A may be split from the first ticket 310 to a third ticketT(3) 314, and a quantity of 1 of item A may remain on the first ticket310. Next, a fractional quantity of 0.5 of item A may be split from thethird ticket 314 (a split ticket) to a fourth ticket T(4) 316 (a splitticket), and a fractional quantity of 0.5 of item A may remain on thethird ticket 314.

FIG. 4 illustrates an example environment 400 that includes differentmerchants 402 operating respective point-of-sale (POS) devices 404 toengage in various transactions with respective customers 406. The POSdevices 404 may comprise any sort of mobile or non-mobile device thatincludes an instance of a merchant application that executes on therespective device. The merchant application may provide POSfunctionality to the POS device 404 to enable the merchant 402 (e.g., anowner, employees, etc.) to accept payments from the customers 406. Insome types of businesses, one such POS device 404 may correspond to astore or other place of business of the merchant, and thus, may be afixed location that typically does not change on a day-to-day basis. Inother types of businesses, however, the POS device 404 may change fromtime to time, such as in the case that the merchant operates a foodtruck, is a street vendor, a cab driver, etc., or has an otherwisemobile business, e.g., in the case of merchants who sell items atbuyer's homes, places of business, and so forth.

As used herein, a merchant 402 may include any business engaged in theoffering of goods or services for acquisition by customers. Actionsattributed to a merchant 402 may include actions performed by owners,employees, or other agents of the merchant 402 and thus no distinctionis made herein unless specifically discussed. In addition, as usedherein, a customer 406 may include any entity that acquires goods orservices from a merchant, such as by purchasing, renting, leasing,borrowing, licensing, or the like. Hereinafter, goods and/or servicesoffered by merchants 402 may be referred to as items. Thus, a merchant402 and a customer 406 may interact with each other to conduct atransaction in which the customer 406 acquires an item from a merchant402, and in return, the customer 406 provides payment to the merchant402.

As used herein, a transaction may include a financial transaction forthe acquisition of goods and/or services that is conducted between acustomer 406 and a merchant 402. For example, when paying for atransaction, the customer 406 can provide the amount that is due to themerchant 402 using a payment instrument (e.g., a debit card, a creditcard, a stored-value or gift card, a check, through an electronicpayment application on a device carried by the customer, or the like).The merchant 402 can interact with the POS device 404 to process thetransaction, such as by inputting (e.g., manually, via a magnetic cardreader or an RFID reader, etc.) an identifier associated with thepayment instrument. For example, a payment instrument of one of thecustomers 406 may include one or more magnetic strips for providing cardand customer information when swiped in a card reader. On otherinstances, the payment instrument of the customer 406 may include a chipthat is read by the card reader when the card is dipped into the cardreader. In other examples, other types of payment cards may be used,such as smart cards having a built-in memory chip, a radiofrequencyidentification tag, or so forth.

During the transaction, the POS device 404 can determine transactioninformation describing the transaction, such as the identifier of thepayment instrument, an amount of payment received from the customer 406,the item(s) acquired by the customer, a time, place and date of thetransaction, and so forth. The POS device 404 can send the transactioninformation to a payment service 408 over a network 410, eithersubstantially contemporaneously with the conducting of the transaction(in the case of online transactions) or later when the POS device 404 isin the online mode (in the case offline transactions).

In an offline transaction, the POS device 404 may store one or morecharacteristics associated with the transaction (i.e., the transactioninformation), such as a cost of the transaction, a time of day at whichthe transaction occurred, a day of the week at which the transactionoccurred, a location at which the transaction took place, an item thatthe customer obtained, and a payment instrument used in the transaction.After conducting an offline transaction with one of the customers 406,the POS device 404 may provide the stored information to the paymentservice 408 over the network 410. The network 410 may represent any oneor more wired or wireless networks, such as a WiFi network, a cellularnetwork, or the like.

In some instances, the POS devices 404 of the merchants 402 may maintainopen ticket and/or split data structure, which may record interactionsmade between a customer 406 and a respective merchant 402. For instance,the open ticket data structures described herein may be generated andmaintained using some or all of the techniques described in U.S. patentapplication Ser. No. 14/686,381, filed on Apr. 14, 2015 and entitled“Open Ticket Payment Handling with Offline Mode”, which is incorporatedherein by reference in its entirety. In some implementations, the splitticket data structure may be the same as, or similar to, the open ticketdata structure.

When a customer 406 orders an item, the merchant 402 may enter the iteminto the POS device 404, which may update the open ticket data structureto note the ordered item and a time at which the item was ordered. Inaddition, the merchant may insert free-form notes into the open ticketdata structure, such as a note documenting a verbal exchange between thecustomer 406 and the merchant 402 or a sentiment of the customer 406 asperceived by the merchant 402. In still other instances, the POS device404 of the respective merchant 402 may store multiple tags each denotinga respective typical interaction between merchants 402 and customers406, such as accepted refill, requested water, requested check, appearshappy, appears displeased, or the like. Again, the open ticket datastructure may be updated when receiving a free-form note or a tag toindicate a time at which that record was received. In addition, when acustomer 406 offers tender (e.g., cash, a gift card, a check, a creditcard, etc.) to pay for one or more items acquired from the merchant 402,the merchant 402 may update the open ticket data structure on the POSdevice 404 of the merchant 402 to indicate this payment. Again, the POSdevice 404 may indicate a time at which the payment was received.

Proximate to a merchant 402 and a customer 406 ending an engagement(e.g., after settling a cost of the items and/or after the customerreceives the last ordered item), the merchant 402 may provide thecontents of the open ticket data structure to the payments service 408for analysis. As illustrated, multiple merchants may send respectivetickets 412, including open tickets and/or split tickets, to the paymentservice 408 for analysis. The payments service 408 may analyze the itemsordered, the tenders used, the notes, the tags, and the respective timesand sequences of these interactions represented in the open ticket datastructure to determine certain preferences or habits of customersgenerally or of particular customers. With this information, thepayments service 408 may then send split ticket suggestions 414 to thePOS devices 404 of the merchants 402, as described in further detailbelow. In some instances, the merchants 402 send the respective tickets412 to the payments service 408 upon closure of the respective tickets.In other instances, the contents of these tickets may provided as therespective merchant 402 updates the respective ticket. That is, thecontents of the ticket as modified on a respective POS device 404 may besynchronized with the contents of the ticket at the payments service408.

After closure of a ticket (or as part of the payment authorizationrequest), the POS device 404 may provide the contents of the ticket tothe payments service 408. The payments service 408 may analyze thesecontents to determine any preferences or habits of customers generallyand/or of a particular customer. By doing so, the payments service 408may provide real-time split ticket suggestions to the merchant 402

The payments service 408 may include one or more processors and memory,which may store a ticket-creation module 416, a payment processingmodule 418, a ticket-analysis module 420, a split ticket handling module120, a split ticket suggestion module 122, merchant profiles 422corresponding to respective merchants, customer profiles 424corresponding to respective customers, and tickets 426 includingcontents of prior open tickets and/or prior split tickets. Theticket-creation module 416 may trigger creation of an open ticket basedon any one of multiple triggers. In one particular example, when acustomer requests to create a reservation at a particular merchant, theticket-creation module 416 may send an indication to a device of amerchant indicating the details of the reservation request. In response,the device of the merchant may generate an open ticket for recordingsubsequent interactions between the customer and the merchant.

The payment processing module 418, meanwhile, may function to receivethe information regarding a transaction from the POS device 404 andattempt to authorize the payment instrument used to conduct thetransaction. The payment processing module 418 may then send anindication of whether the payment instrument has been approved ordeclined back to the POS device 404.

Generally, when a customer 406 and a merchant 402 enter into anelectronic payment transaction, the transaction is processed byelectronically transferring funds from a financial account associatedwith the customer 406 to a financial account associated with themerchant 402. As such, the payment processing module 418 may communicatewith one or more computing devices of a card payment network, e.g.,MasterCard®, VISA®, over the network 410 to conduct financialtransactions electronically. The payment processing module 418 can alsocommunicate with one or more computing devices of one or more banks overthe network 410. For example, the payment processing module 418 maycommunicate with an acquiring bank, and/or an issuing bank, and/or abank maintaining customer accounts for electronic payments.

An acquiring bank may be a registered member of a card association(e.g., Visa®, MasterCard®), and may be part of a card payment network.An issuing bank may issue credit cards to buyers, and may pay acquiringbanks for purchases made by cardholders to which the issuing bank hasissued a payment card. Accordingly, in some examples, the computingdevice(s) of an acquiring bank may be included in the card paymentnetwork and may communicate with the computing devices of a card-issuingbank to obtain payment. Further, in some examples, the customer may usea debit card instead of a credit card, in which case, the bank computingdevice(s) of a bank corresponding to the debit card may receivecommunications regarding a transaction in which the customer isparticipating. Additionally, there may be computing devices of otherfinancial institutions involved in some types of transactions or inalternative system architectures, and thus, the foregoing are merelyseveral examples for discussion purposes.

The ticket-analysis module 420, meanwhile, may function to receivetickets, store them in the data store 426, and analyze the tickets todetermine preferences and/or habits of customers. For instance, and asdescribed in further detail below, the ticket-analysis module 420 mayanalyze items ordered, notes and tags within the tickets, and the timingof these events to determine these preferences and habits. In instanceswhere a particular analysis is associated with a particular customer,the ticket-analysis module 420 may store this determined preference orhabit in association with the corresponding customer profile in the datastore 424.

The split ticket handling module 120 may provide the functionalitydescribed herein with respect to split ticket handling. A split tickethandling module 120 may also reside on a POS device 404 to facilitatethe coordination of ticket handling between the POS device and thepayments service. In some cases, the split ticket handling module 120may function to handle split tickets in the manner described withreference to FIGS. 1, 2A-2E, 3A-3C, and 5.

The split ticket suggestion module 122 may function to provide splitticket suggestions 414 as described herein. For instance, the splitticket suggestion module 122 may utilize analyses of the ticket-analysismodule in determining split ticket suggestions 414. As discussed infurther detail below with reference to FIGS. 6-9, the split ticketsuggestion module 122 may, in some cases, suggest to split one or moreitems from a first ticket to a second ticket based at least in part onone or more of merchant information (e.g., merchant profiles 422),customer information (e.g., customer profiles 424), or ticketinformation (e.g., tickets 426).

FIG. 5 is a flow diagram illustrating an example process 500 forhandling ticket splitting, as described in further detail above withreference to FIGS. 1-4. The process 500 and other processes describedherein are illustrated as collections of blocks in logical flowdiagrams, which represent a sequence of operations, some or all of whichcan be implemented in hardware, software or a combination thereof. Inthe context of software, the blocks may represent computer-executableinstructions stored on one or more computer-readable media that, whenexecuted by one or more processors, program the processors to performthe recited operations. Generally, computer-executable instructionsinclude routines, programs, objects, components, data structures and thelike that perform particular functions or implement particular datatypes. The order in which the blocks are described should not beconstrued as a limitation. Any number of the described blocks can becombined in any order and/or in parallel to implement the process, oralternative processes, and not all of the blocks need be executed. Fordiscussion purposes, the processes are described with reference to theenvironments, architectures and systems described in the examplesherein, although the processes may be implemented in a wide variety ofother environments, architectures and systems.

At 502, the process 500 may receive one or more inputs indicating a setof items. These one or more inputs may be received at least partly via auser interface (UI) of a point-of-sale (POS) device. The set of itemsmay correspond to items that have been ordered by one or more customersfrom a merchant associated with the POS device. For example, the set ofitems may correspond to menu items ordered by customers at a restaurant.

At 504, the process 500 may generate a first ticket associated with theset of items. For instance, the first ticket may be an open ticket. Thefirst ticket may be generated at least partly via the POS device. Insome cases, the first ticket may be generated while the POS device isoperating in an open ticket mode configured to facilitate the generationof open tickets.

At 506, the process 500 may receive one or more inputs designating atleast one item to be split from the first ticket to a second ticket.These one or more inputs may be received at least partly via the UI ofthe POS device. For example, the set of items of the first ticket maycorrespond to items requested by multiple customers on an open ticket.The customers may request to pay individually for their respectiveitems, or the customers may request that the customer split the items ontheir open ticket in any other manner that suits them.

In some instances, the merchant associated with the POS device, or thePOS device itself, may determine to split one or more items from thefirst ticket to the second ticket. For example, the POS device mayreceive a split ticket suggestion from one or more computing devicesthat are associated with a third party payments service and that areconfigured to process payments for multiple merchants. The split ticketsuggestion may be the one or more inputs that cause the POS device tosplit one or more items from the first ticket to the second ticket. Insome cases, the split ticket suggestion may cause the POS to provide anindication corresponding to the suggestion at least partly via the UI ofthe POS device, and the merchant may determine to provide, to the POSdevice, one or more inputs that cause the POS device to split one ormore items from the first ticket to the second ticket.

The POS device may provide (e.g., via the UI) an option to initiate asplit ticket mode of the POS device. That is, the POS device may beconfigured to be operable in an open ticket mode and in a split ticketmode. The POS device may be transitioned to the split ticket modemanually and/or automatically.

At 508, the process 500 may send a first message that causes one or morecomputing devices to generate a first foster ticket. The first messagemay be sent from the POS device to one or more computing devicesassociated with the payments service. The first foster ticket may beassociated with the first ticket and the set of items. The one or morecomputing devices associated with the payments service may be configuredto use foster tickets to account for items and/or tickets at the POSdevice. For instance, the first foster ticket may be used to account foritems capable of being manipulated at least partly via the UI of the POSdevice. In some cases, the one or more computing devices associated withthe payments service may generate the first foster ticket in response tobeing notified that the first ticket has been generated. In other cases,the one or more computing devices associated with the payments servicemay generate the first foster ticket in response to being notified thatthe split ticket mode has been initiated and/or in response to beingnotified that one or more items have been split from the first ticket tothe second ticket.

At 510, the process 500 may receive one or more inputs corresponding toan action the changes a state of the first ticket or the second ticket.In some cases, these one or more inputs may be received at least partlyvia the UI of the POS device. For instance, the one or more inputs maycorrespond to a save of the first ticket and/or the second ticket, acancel of the first ticket and/or the second ticket, a print of thefirst ticket and/or the second ticket, a closing out of the first ticketand/or second ticket, or the like.

At 512, the process 500 may send a second message that causes one ormore computing devices to update the first foster ticket. Alternatively,the process 500 may, at 514, send a second message that causes one ormore computing devices to replace the first foster ticket with a secondfoster ticket. For instance, the second message may be sent from the POSdevice to the one or more computing devices associated with the paymentsservice. The second message may be sent to the one or more computingdevices in response to receiving one or more inputs corresponding to anaction that changes a state of a ticket. For instance, the secondmessage may be sent to the one or more computing devices in response toreceiving one or more inputs corresponding to a save of the first ticketor the second ticket.

In some cases, updating the first foster ticket may include replacingthe first foster ticket with the second foster ticket. However, in othercases, updating the first foster ticket may include modifying the itemswith which the first foster ticket is associated and/or modifying theticket with which the first foster ticket is associated.

When the second foster ticket replaces the first foster ticket, thesecond foster ticket may be associated with at least one ticketremaining in the UI of the POS device. In some instances, the secondfoster ticket may be associated with a lowest ordinal ticket remainingin the UI of the POS device. For example, the second foster ticket maybe associated with the second ticket in the UI of the POS device inresponse to a save of the first ticket in the UI (which, in some cases,may also result in the first ticket being dismissed from the UI). Thesecond ticket may be associated with a first identifier, while thesecond foster ticket may be assigned a second identifier that iscorrelated to the first identifier. For instance, the first identifierand the second identifier may be the same.

FIG. 6 is a flow diagram illustrating an example process 600 forproviding an indication of candidate items for ticket splitting. At 602,the process 600 may receive, from a merchant device, a list of itemsassociated with a first ticket. In some cases, the merchant device maybe a first merchant device associated with a first merchant.Furthermore, the first ticket may be an open ticket that was generatedat least partly via the first merchant device.

The list of items may be received at a one or more computing devicesthat process payments for multiple merchants including the firstmerchant. In some cases, the one or more computing devices may receive,from the first merchant device, ticket information including the firstticket and the list of items associated with the first ticket.

At 604, the process 600 may determine that one or more items satisfy oneor more flagging criteria that identify candidate items for ticketsplitting. This determination may occur, for example, in response todetermining that the list of items and/or the first ticket areassociated with multiple customers. However, in some cases, thedetermination may be triggered by a different action or may occur bydefault.

In some cases, a determination that an item of the list of itemssatisfies a flagging criterion may include comparing the list of itemsto historical ticket information. For instance, the list of items may becompared to historical ticket splitting information.

In some examples, a determination that an item of the list of itemssatisfies a flagging criterion may include comparing the first ticket toa set of split tickets. For instance, a determination that an item ofthe list of items satisfies a flagging criterion may include calculatinga similarity score corresponding to a similarity between a split ticketof the set of split tickets. The determination may also includedetermining that the similarity score satisfies a similarity threshold.One or more items of the list of items may be identified as candidateitems for ticket splitting based at least in part ticket informationassociated with the split ticket that has a similarity score thatsatisfies the similarity threshold.

Additionally or alternatively, a determination that an item of the listof items satisfies a flagging criterion may include determining one ormore split tickets of the set of split tickets that are nearestneighbors of the first ticket. One or more items of the list of itemsmay be identified as candidate items for ticket splitting based at leastin part on determining the one or more nearest neighbor split tickets.

In some instances, the one or more computing devices may receive ticketinformation from one or more merchant devices including a secondmerchant device associated with a second merchant that is different thanthe first merchant. The determination that one or more items of the listof items satisfy one or more flagging criteria may be based at least inpart on the ticket information received from the one or more merchantdevices.

The one or more flagging criteria may include at least one flaggingcriterion that identifies candidate items that can be split on afractional basis. For instance, the flagging criterion may identify anitem is of a type that is typically split amongst multiple people, suchas an appetizer.

At 606, the process 600 may send, to the merchant device, an indicationindicating the candidate items for ticket splitting. In some cases, theone or more computing devices may send an indication that causes themerchant device to provide a suggestion at least partly via a userinterface (UI) presented on a display of the merchant device. In somecases, the indication may cause the merchant device to present, at leastpartly via the UI, a suggestion to split one or more items from thefirst ticket to a second ticket. Additionally or alternatively, theindication may cause the merchant device to provide a visual indicationindicating one or more items identified as candidate items for ticketsplitting. In some instances, the indication may cause the merchantdevice to provide an audible suggestion to split one or more items ofthe list of items from the first ticket to a second ticket.

FIG. 7 is a flow diagram illustrating an example process 700 forproviding a split ticket suggestion. At 702, the process 700 may receivesplit ticket information from one or more point-of-sale (POS) devices.In some cases, the split ticket information may be received at one ormore computing devices associated with a payments service. The splitticket information may be associated with split tickets generated atleast partly via one or more POS devices.

At 704, the process 700 may determine that at least two types of itemsare commonly included in a number of split tickets. In some cases, theone or more computing devices associated with the payments service maydetermine that a first item and a second item are commonly included in anumber of split tickets based at least in part on the split ticketinformation received from the one or more POS devices.

At 706, the process 700 may determine that the at least two types ofitems satisfy a suggestion threshold. For instance, the one or morecomputing devices associated with the payments service may determinethat the first type of item and the second type of item satisfy asuggestion threshold based at least in part on the number of splittickets in which the first type of item and the second type of item arecommonly included.

At 708, the process 700 may store a split ticket flag associated withthe at least two types of items. For example, the split ticket flag maybe stored in a database. The database may be accessible to the one ormore computing devices associated with the payments service so that theone or more computing devices can use the split ticket flag to providesplit ticket suggestions.

At 710, the process 700 may receive, from a POS device, a list of itemsassociated with an open ticket. The open ticket may be generated atleast partly via the POS device. The list of items may be received atthe one or more computing devices associated with the payments service.Furthermore, the list of items may include a first item and a seconditem.

At 712, the process 700 may determine that the first item of the openticket is of the first type of item. For instance, the one or morecomputing devices associated with the payments service may determine,based at least in part on the split ticket flag, that the first item ofthe open ticket is of the first type of item associated with the splitticket flag. At 714, the process 700 may determine that the second itemof the open ticket is of the second type of item. For instance, the oneor more computing devices associated with the payments service maydetermine, based at least in part on the split ticket flag, that thesecond item of the open ticket is of the second type of item associatedwith the split ticket flag.

At 716, the process 700 may send, to the POS device, a split ticketsuggestion that causes the POS device to suggest to split at least thefirst item and the second item from the open ticket to a new splitticket. In some cases, the split ticket suggestion may cause the POSdevice to provide a suggestion at least partly via a user interface (UI)presented on a display of the POS device. The split ticket suggestionmay be sent based at least in part on the split ticket flag stored inthe database. In some instances, the split ticket flag may be sent bythe one or more computing devices associated with the payments service.For instance, the one or more computing devices may send the splitticket suggestion to the POS device in response to receiving a requestfor a split ticket suggestion. However, in some instances, the one ormore computing devices may send the split ticket suggestion to the POSdevice without receiving a request for a split ticket suggestion.

In some cases, the one or more computing devices associated with thepayments service may receive split ticket suggestion feedback from thePOS device. For example, the one or more computing devices may receive,from the POS device, an indication indicating whether the split ticketsuggestion actually resulted in the first item and the second item beingsplit from the open ticket to a new split ticket. In such cases, the oneor more computing devices may again determine, based at least in part onthe indication, whether the first type of item and the second type ofitem continue to satisfy the suggestion threshold. That is, the one ormore computing devices may utilize split ticket suggestion feedbackreceived from one or more POS devices to update split ticket flagsstored in the database.

FIG. 8 is a flow diagram illustrating another example process 800 forproviding an indication of candidate items for ticket splitting. At 802,the process 800 may receive ticket information associated with a ticket.For instance, one or more computing devices associated with a paymentsservice may receive the ticket information from a merchant device. Theticket information may include a list of items of the ticket and anindication of one or more customers associated with the ticket.

At 804, the process 800 may identify a customer associated with theticket. For example, the one or more computing devices associated withthe payments service may identify the customer based at least in part onthe ticket information. In some cases, the one or more computing devicesmay access customer profiles and determine that an identificationassociated with the customer in the customer profiles is correlated withan identification associated with the customer in the ticketinformation.

At 806, the process 800 may obtain customer information corresponding tothe customer. The customer information may include historical ticketinformation associated with the customer. In some instances, the one ormore computing devices associated with the payments service may obtaincustomer information corresponding to the customer from data stores thatinclude customer profiles, ticket information, and/or other informationassociated with customers.

At 808, the process 800 may designate one or more items of the ticket ascandidate items for ticket splitting. For instance, the one or morecomputing devices associated with the payments service may designate oneor more items of the ticket as candidate items for ticket splittingbased at least in part on the customer information associated with thecustomer. In some cases, the one or more computing devices mayadditionally or alternatively designate one or more items of the ticketas candidate items for ticket splitting based at least in part on splitticket information received from one or more merchant devices.

At 810, the process 800 may send, to a merchant device, an indicationindicating the candidate items for ticket splitting. In some cases, theone or more computing devices associated with the payments service maysend the indication to the merchant device. The indication may cause themerchant device to present a prompt corresponding to a suggestion tosplit an item from the ticket to another ticket.

FIG. 9 is a flow diagram illustrating another example process 900 forproviding a split ticket suggestion. At 902, the process 900 may receiveticket information from one or more point-of-sale (POS) devices. Theticket information may be associated with tickets generated at leastpartly via the one or more POS devices. One or more of the tickets mayindicate associations between items and customers. In some cases, one ormore computing devices associated with a payments service may receivethe ticket information from the one or more POS devices. In someinstances, the one or more POS devices may include a first POS deviceassociated with a first merchant, and a second POS device associatedwith a second merchant. The second merchant may be different than thefirst merchant.

At 904, the process 900 may determine that a first ticket received fromthe one or more POS devices indicates an association between a firsttype of item and a customer. For instance, the one or more computingdevices associated with the payments service may determine that thefirst ticket indicates an association between the first type of item andthe customer based at least in part on the ticket information.Furthermore, the process 900 may, at 906 determine that the first ticketindicates an association between a second type of item and the customer.For instance, the one or more computing devices may determine that thefirst ticket indicates an association between the second type of itemand the customer based at least in part on the ticket information. At908, the process 900 may store a split ticket flag associated with thecustomer, the first type of item, and the second type of item.

At 910, the process 900 may receive, from a POS device, a list of itemsincluding a first item and a second item. For example, the one or morecomputing devices associated with the payments service may receive thelist of items from the second POS device. The list of items may indicatean association between the first item and the customer. Furthermore, thelist of items may indicate an association between the second item andthe customer.

At 912, the process 900 may determine that the first item is of thefirst type of item. For instance, the one or more computing devicesassociated with the payments service may determine that the first itemis of the first type of item based at least in part on the split ticketflag associated with the customer. Furthermore, the process 900 may, at914, determine that the second item is of the second type of item. Forinstance, the one or more computing devices may determine that thesecond item is of the second type of item based at least in part on thesplit ticket flag associated with the customer.

At 916, the process 900 may send, to the POS device, the message thatcauses the POS device to suggest to split at least the first item andthe second item from an open ticket to a new split ticket. For example,the one or more computing devices may send the message to the second POSdevice based at least in part on the split ticket flag stored associatedwith the customer.
